Seeking 2.5in. SSD hybrid drive compatible with Optical Bay Enclosure?

I want to replace the super drive in my iMac another hard drive. Would like to find a 2.5in. SSD that will go in the 12.7 mm SATA Optical Bay SATA Hard Drive Enclosure that can be put into this machine. Can anybody recommend a compatible drive for this application? It can be the drive only, or a kit similar to this one:

You have the correct parts listed here the carrier and a HD that will fit the carrier.

From the writeup this appears to be the Seagate 2.5" SSHD (hybrid) that works with SATA I (1.5 Gb/s), II (3.0 Gb/s) & III (6.0 Gb/s) so it will work just fine in your system. Here's the spec sheet from Seagate: Laptop SSHD

Frankly, I would recommend upgrading the main HD to a Seagate 3.5" SSHD. Review this: Seagate Desktop SSHD & here is the Spec sheet for the drive series Desktop SSHD This drive will work with your system without any problems (don't forget to take your thermal sensor off your old drive). Doing this will give you better performance and will be less work.

If you don't want to upgrade your current drive then I would go with a straight SSD Vs a SSHD for the second drive.

If you can try to get an external FireWire HD case to hold your old drive and make upgrading a breeze.

Update

Apple uses a few different sources for their HD's (Seagate, Toshiba & Western Digital).

The issue is more of the SATA I/O speed (SATA I, II or III) the system has and what the given HD you want to use is able to work in your system. The next issue is the given size of the drive (2.5" laptop class vs 3.5" desktop class) as well as the drives height if the space is limited and in laptops. You might encounter one issue which is the power connector/thermal sensor cable may need to be swapped if it has an integrated sensor Vs an external sensor or you are trying a different vendors drive from what the cable was designed to work with. As it turns out its not a big deal to swap out the cable to the other type.

If your system is still able to boot up. You can find out what HD you have via the About This Mac under the Apple menu, then clicking on More Info button then click the System Report button a new window will pop up with the report expand the hardware twisty and click on Storage. Under Physical Drive: copy the Media Name and do a google search for it it should tell you what the make and model of the drive you currently have in your system.

You can use EveryMac using your serial number you should be able to get more details of your system. Sadly, it won't tell you who's HD you have. You will need to open the system to find out if its dead.

The debate of Seagate Vs WD is pointless both make good drives and both have been stung with a bad run of drives. I would focus on what features and specs a given drive has that you are looking for. We use both as replacements depending on what we are looking for.

Given your primary drive is dead, I would take the quicker and easier path just replace it with the SSHD.

Thanks for your response Dan. I actually have to replace my primary drive...it is dead; that is what started all of this. I was considering what you suggest, but then I was concerned because the drive I was looking at https://www.ifixit.com/Store/Mac/2-TB-SS... indicates that the replacement drive is the same make as the one that originally came in the iMac, and just yet I am unsure what is inside. (Doesn't Apple usually ship with Western Digital drives rather than Seagate?) Hate to order the Seagate SSHD without being sure... Would like to get a straight SSD for the secondary drive, just not sure I want to spend the money. Do you know if the upgrade kit for a straight SSD will have everything I need to add it to the Optical Drive enclosure unit? as they appear to be a different size, etc.. Again, thanks for your input.

Your optical drive carrier supports a laptop class drive (2.5") not a desktop (3.5"). make sure you are getting the correct drive here if you are ADDING a second HD (or SSD). FYI - You'll need to first address your primary drive problem.

Yes, I am aware of that. My DVD super drive died some time ago, so I figured while I had the thing open I should go ahead and add a second drive. I should be able to install them both and then set up the primary drive first with a bootable Mavericks install, right? Once that is set I can set up the secondary...or at least that is my plan.

One last question...this statement concerning compatibility pulled from the ifixit site:

Important: To ensure compatibility with the 2009 and 2010 21.5" or 27" iMac, the replacement hard drive must be of the same brand as the original. The model number of the hard drive does not matter as long as the brand matches.

When it says "same brand", what should I be looking for in my replacement drive? Does this mean if there is a WD drive in my machine I must replace it with a WD drive and not a Seagate, or is it more a matter of speed as you mention above? If that is the case where will this information be listed as I shop for drives?

Thanks again...I hate this part. I just want to pick compatible components so that I can get to work :)

The 'replace with like vendor' is the custom thermal sensor cable issue I spoke about. You ca still change out the drive to a different vendor, you will just need to swap out the harness, which is not that big a deal.

These are the components I found for purchase:

Accompanying 2.5 inch drive to go in new Optical Bay enclosure

What do you think...am I missing anything? If I get the drives alone without a kit will I be missing any necessary cables or harness you mention for the upgrade? I really appreciate the help!

That should do it. The only thing will be the custom cable harness for the primary HD if you find you have a WD drive, you'll need to order the 922-9224 Seagate drive temp sensor cable.
